IP address is a numerical label for devices connected to internet-using networks. IP addresses serve both network interface identification and location addressing. IPv4 was first introduced in 1983, IPv6 in 1995
IP is a protocol that enables devices to communicate over networks. Every device on the Internet is assigned a unique IP address. Data packets are broken down into smaller chunks for routing
IPv6 offers 128-bit addressing for better security and mobility. IPv4 address space is running out, making IPv6 necessary. Many websites will permanently enable IPv6 connectivity after June 2012
Website provides instant IP address lookup for home and VPN users. Founded by Chris Parker in mid-nineties to simplify IP address finding. Shows both IPv4 and IPv6 addresses for public viewing
Users report issues with IPv4 connectivity while IPv6 works fine. Problem occurs when device receives only IPv4 or IPv6 address
IPv6 is a newer network standard for larger device connectivity. Devices may receive both IPv4 and IPv6 addresses when connected. Network must support IPv6 connections for proper functioning
